Deleting iMovie project that says null
Hi, I deleted some of the folders inside the iMovie library package. When I load up the library, the folders I deleted are still shown in the project window as "null" projects and I cannot delete it. Help! What I'm trying to do is delete those projects from the iMovie project window so it doesn't clutter up the screen. Thank you!
The version I am using is 10.1.12 on High Sierra 10.13.6
Windows, Windows 6
